WOVEN-WIRE MATTRESS.

SPECIFICATION forming part of Letters Patent No. 756,143, dated March 29, 1904.

Application'filed May 8, 1903. Serial No. 156,290. (No model.)

T0 at whom, it may concern:

York, in the Province of Ontario, Canada,

have invented certain new and useful 1mprovements in Woven-Wire Mattresses, of which the following is a specification.

My invention relates to improvements in woven-wire fabrics particularly adapted to matresses; and the object of the present invention is to so improve the construction of the fabric as to allow of suflicient resiliency, and yet limit the amount of sag to the mattress when made up; and it consists, essentially, ofa series of coils of wire longitudinally arranged and interlocking with one another and a series of supplemental coils, preferably of double the pitch of the ordinary coils,such latter coils being interlaced in the ordinary coils and interlocking with each other throughout the length, as hereinafter more particularly explained.

The drawing represents a plan view of my improved fabric;

A represents a series of primary left-hand spirally wound or coiled interlocking wires, each coil of which interlocks with its adjacent coil from end to end, as indicated.

B represents a series of supplemental or secondary right-hand spirally wound or coiled Wires, each coil being, preferably, of double the pitch of the ordinary coils A. y

The coils B are interlaced through each alternate coil of the coils A, first passing through the coil of one length and the coil of the adjacent length alternately and being interlocked with the supplemental adjacent coil B at the point where the supplemental coils are interlaced in the adjacent coil.

By such a construction as I have described I am enabled when my fabric is used for bedbottoms to produce a fabric of sufiicient resiliency and having a minimum sag to make a comfortable mattress.

In making my improved mattress fabric the left-hand coils are all made first and interlocked with each other and then the righthand double-pitch coils are interlaced through the previously-made fabric and interlocked with each other as they are being interlaced.

What I claim as my invention is In a woven fabric, the combination with a pair of coiled wires A extending parallel with each other and having their coils interlocked, and a third wire B of greater pitch than and running in the same direction as the wires A, said wire B being threaded first through a coil of one of the wires A and then through a coil ofthe other wire A the points of connection between said wire B and each wireA being alternate in respect to the coils of said wire.
